Multimessenger astronomy with the Pierre Auger Obser- vatory — •Marcus Niechciol for the Pierre Auger collaboration — Center for Particle Physics Siegen, Experimentelle Astroteilchen- physik, Universität Siegen

The Pierre Auger Observatory is the largest air-shower experiment in the world, offering an unprecedented exposure not only to charged cosmic rays, but also to neutral particles at the highest energies. The Observatory can therefore contribute significantly to current efforts in multimessenger astronomy. For example, the upper limits on the incoming flux of ultra-high-energy (UHE) photons and neutrinos de- termined from Auger data are the most stringent to date, severely con- straining current models for the origin of UHE cosmic rays. Follow-up searches for neutral particles in association with gravitational wave events and other transient events, such as the anomalous blazar TXS 0506+056, complement those performed by specialized instruments at lower energies, extending the energy range of current multimessenger studies to the UHE regime.

In the contribution, the various activities concerning multimessen- ger astronomy at the Pierre Auger Observatory are presented and the current results are summarized. In addition, future perspectives in the scope of the ongoing AugerPrime upgrade will be discussed.
